IMFAR, the autism numbers game and 12% showing 'optimal outcome'

by Paul Whiteley in Questioning Answers

A post recently published on the Spectrum website led to my blogging entry today, and the observation that: 'Alternative screen finds high autism prevalence in U.S. state'.Discussing results delivered at IMFAR 2017 the research in question was that presented by Laura Carpenter and colleagues [1] (someone with quite a track record in autism research). This was a conference presentation and seemingly not yet peer-reviewed publication, so one needs to be a little cautious about making big clai........ Read more »

Intestinal dysbiosis, irritable bowel syndrome and ME/CFS

by Paul Whiteley in Questioning Answers

I don't want to spend too much time talking about yet another paper from the research tag-team that is Hornig & Lipkin [1] (open-access) on the topic of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). But this latest addition to their research repertoire (see here) is deserving of several comments.Not least are the observations made by the authors - including one Brent Williams who some might remember from autism research history (see here) and Jose Montoya who has als........

Looking for Empathy in All the Wrong Places: Bizarre Cases of Factitious Disorder

by The Neurocritic in The Neurocritic

art by Zdzisław Beksiński Factitious disorder is a rare psychiatric condition where an individual deliberately induces or fabricates an ailment because of a desire to fulfill the role of a sick person. This differs from garden variety malingering, where an individual feigns illness for secondary gain (drug seeking, financial gain, avoidance of work, etc.). The primary goal in factitious disorder is to garner attention and sympathy from caregivers and medical staff.The psychiatric handbook DSM-........ Read more »

Welcoming zonulin into autism research

by Paul Whiteley in Questioning Answers

I was VERY happy to read the paper published by Erman Esnafoglu and colleagues [1] suggesting that: "zonulin, which regulates intestinal permeability, plays a role in the development of symptoms of ASD [autism spectrum disorder]."Zonulin - something that "can be used as a biomarker of impaired gut barrier function for several autoimmune, neurodegenerative, and tumoral diseases" [2] - is a compound that I've been interested in for a while on this and other blogs (see here). The primary ........ Read more »

Physical exercise as a nootropic of choice

by Paul Whiteley in Questioning Answers

Nootropic, defined as a 'smart drug' or cognitive enhancer, is generally taken to mean a substance/compound/medicine that has some positive effect(s) on aspects of cognition. I've talked about the possibility that various compounds might fit this bill on this blog (see here for example) but today I'm discussing another quite important potential nootropic: exercise.It was the paper by Joseph Michael Northery and colleagues [1] (open-access) that added exercise to the nootropic categoris........

Could an "ill-state" associated with anorexia nervosa mimic the symptoms of autism?

by Paul Whiteley in Questioning Answers

The question posed in the title of this post 'Could an "ill-state" associated with anorexia nervosa mimic the symptoms of autism?' stems from the findings reported by Heather Westwood and colleagues [1] (open-access).They continued a research theme looking at the potential 'overlap' when it comes to autism and eating disorders such as anorexia nervosa (AN) (see here). Notably, researchers questioned whether the finding that some 50% of their cohort "scored above the clinical cut-off on the ........ Read more »

Conviction for violence and autism: comorbidity counts

by Paul Whiteley in Questioning Answers

I tread carefully when discussing the results published by Ragini Heeramun and colleagues [1] on the topic of "whether autism is associated with convictions for violent crimes" and "the associated risk and protective factors." Carefully because, as I've indicated on other occasions (see here), people commit crimes not labels, and sweeping generalisations about labels, specific types of crime and/or the concept of 'dangerousness' tend to do very little to help anyone in the long term.St........

"Medical Conditions in the First Years of Life Associated with Future Diagnosis of ASD"

by Paul Whiteley in Questioning Answers

I rank the paper by Stacey Alexeeff and colleagues [1] (open-access available here) as being in the 'pretty important' category when it comes to hierarchy in autism research. Not only because of their use of data derived from Kaiser Permanente (KP) (quite a large US healthcare provider that has some autism research history) including some "3911 ASD [autism spectrum disorder] cases and 38,609 controls" but also because some of the findings reiterate what is already 'known' abo........

Vitamin D genes and autism

by Paul Whiteley in Questioning Answers

"Vitamin D deficiency is a putative environmental risk factor for autism spectrum disorder (ASD)."And..."We provide straightforward genetic evidences for the first time that VDRGs [vitamin D-related genes] with a strong degree of DNM [de novo mutations] burden in ASD and DNMs of VDRGs could be involved in the mechanism underlying in ASD pathogenesis."That was the research bottom line reported on by Jinchen Li and colleagues [1] examining an important part of the whole 'vitami........

Trends in ADHD medication use in the US and Europe: is this a bad thing?

by Paul Whiteley in Questioning Answers

I don't want to dwell too much on the findings reported by Christian Bachmann and colleagues [1] observing that in five Western countries - Denmark, Germany, the Netherlands, the United Kingdom (UK) and the United States (US) - ADHD (attention-deficit hyperactivity disorder) medication use between 2005/2006-2012 was on the increase. But I do think it is important to mention some of the implications from such figures and some of the positives and negatives associated with such generated........ Read more »

Self-reported sexual attraction and autism

by Paul Whiteley in Questioning Answers

The findings reported by Tamara May and colleagues [1] are discussed today, looking at self-reported sexual attraction and past sexual relationships among adolescents diagnosed with an autism spectrum disorder (ASD) compared with not-autism controls.Asking 14-15 year olds who took part in The Longitudinal Study of Australian Children (94 diagnosed with autism and some 3400 controls) some rather personal questions, researchers reported that: "ASD males reported fewer prior boyfriends/gi........

Artful Paltering: One more way people lie (especially in  negotiations!)

by Rita Handrich in The Jury Room

Back in 2010, we posted on an article called Artful Dodging that talked about how politicians in particular, answer the question they prefer to answer rather than the question you asked. We talked about responding to that strategy in voir dire. Now, we have another article from the same group of researchers and this one […]... Read more »

ADHD and suicide

"There is a positive association between ADHD [attention-deficit hyperactivity disorder] and suicidality in both sexes and in all age groups."So said the results of the systematic review published by Balazs & Kereszteny [1] (open-access available here) who surveyed the recent peer-reviewed literature on the topic between 2011 and 2015. Reporting results based on findings included in 26 papers, authors concluded that suicidality - ideation, behavior, attempts, and suicide ........ Read more »

The illusion of truth (which is why you should never  repeat fake news)

by Rita Handrich in The Jury Room

It’s been all about “fake news” for a while now and here’s a study telling us to just stop talking about it. Well, sort of. What it actually says is even when we have knowledge to the contrary, if we hear something repeated enough—we come to believe it. Hence, our recommendation that we need to […]... Read more »

On abuse exposure and mate selection

by Paul Whiteley in Questioning Answers

The paper by Andrea Roberts and colleagues [1] is offered up for brief discussion today, and a slightly uncomfortable but nonetheless potentially important set of results that "provide evidence that childhood abuse affects mate selection, with implications for offspring health."I tread very carefully with this topic but was intrigued by the findings looking at whether 'offspring health' in the context of the presence of autism or autism spectrum disorder (ASD) might be at least sometimes mediate........
